I have yet to attempt lucidity as I have been researching it, but I may attempt it tonight if I can get some answers to some strange questions that have been bothering me.

What is the relation between astral projection/OBE and lucid dreaming? Is it possible to practice and develop both of these skills without them overlapping? I'm interested in both but do not want to not be able to control when one or the other occurs if that makes sense. Any insight at all is greatly appreciated.
